NECK-YOKE CENTER.

SPECIFICATION forming part of Letters Patent No. 416,680, dated December 3, 1889.

Application filed June 20, 1889.

To aZZ whom it may concern.-

Be it known that I, ADOLPH P. K0011, a citizen of the United States of America, residing at Effingham,in the county of Efiingham and State of Illinois, have invented certain new and useful Improvements in N eck-Yoke Genters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification. I

My invention relates to neck-yoke centers; and it consists 1n the improved construction,

hereinafter described and set forth, whereby.

a simple and efficient arrangement is provided that will not only be cheaper and more satisfactory than previous forms, but dispense entirely with the necessity for employing screws or like fastening devices for connecting the leather holdback to the metal clasp.

In the accompanying drawings, forming part of this specification, Figure 1 is a side view of a neck-yoke center embodying iny improvements. Fig. 2 is a vertical sectional view showing the arrangement of the clamp and the form of the leather sections used for the leather holdback, and Fig. 3 is a section on the line 00 0c of Fig. 1.

The clampAis in the form of a metal casting in a single piece, and consists of the rectangular socket or, having the end walls 6 inclined downwardly in the direction of each other. The said end walls b are each provided at its upper edge with a horizontallyprojecting ear 0, the upper face of which is curved downwardly to correspond with the curved face of the neck-yoke. Said ear 0 is vertically perforated and is countersunk on its under side to enable the receiving-screw to bear snugly therein.

The leather holdback Bis made up of a series of parallel thicknesses d of leather, each of which presents the outline of the holdback. The said sections d of the holdback are con- Serial No. 314,943. (No model.)

nected rigidly together by both riveting and stitching, and the form of the holdback made thereby is such that its edges e are vertically .parallel until they reach the portion 0, which occupies the casting, at which point the said edges are flaring, so that said portion 0 will be of gradually-increasing width. The depth of the leather holdback is also augmented at said portion 0 by the introduction of internal wedge-shaped leather sections f, located between the central thicknesses (Z.

perforations. I

The thickness d of the holdback may be readily produced and renewed when necessary. The portion a of the casting is also contracted in cross-section to provide for the increased depth of the portion 0, previously alluded to.

I claim- The combination, in a neck-yoke center, of the metal clamp having the inwardlyinclined end walls provided with horizontal perforated ears, a holdback having a main portion of a width corresponding with the narrowest portion of the clamp between the end walls, and

having an enlarged portion 0 with flaring edges, substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
